Safety valves are designed to protect installations and equipment from overpressure. When the system pressure exceeds the set value, the valve opens automatically to release fluid and reduce the pressure, preventing damage or system failure.
The main function of safety valves is to protect equipment, pipes, and pressure vessels from overpressures caused by control failures, temperature increases, system blockages, or changes in operating conditions.
The valve remains closed while the pressure is within normal limits. When the set pressure is exceeded, it opens automatically to release some of the fluid. Once the pressure returns to safe levels, the valve closes again, maintaining system equilibrium.
Safety valves are used in any system that works under pressure, such as: hydraulic systems, boilers and tanks, industrial fluid installations or pneumatic equipment.
Among its main benefits are:
To select the right valve, it is important to consider:
Yes, it is advisable to carry out regular checks to ensure they are functioning correctly, as they are a critical safety element. A poorly calibrated valve may not operate when needed.
Because it protects both the installation and the people inside. It is a mandatory component in many pressure systems and acts as the last line of defense against critical failures.
Both protect against overpressure, but the safety valve usually opens quickly when a limit is reached, while the relief valve regulates system pressure more gradually.
The set pressure is the pressure at which the valve has been adjusted to open. This value must be selected according to the characteristics and operating limits of the system to be protected.
